Its simple I could easyer make a new compile script myself than get the other compilers to work on windows.

The other compilers either use jQuery (with won't build for me on windows), or slack behind the current ember / handlebars version so much I kept running in to trouble every time I wanted to update to the next ember release. I build this script in 2 day's (3 hours to figure out howto compile ember, 1 hour for writing the script and the other time for figuring out how to bundle and publish stuf to npm).

I just took the 'ember-handlebars-compiler' module, patched it so it would work standalone in nodes and there I had my own compile script. Easy to keep up to date and easy to install. O and easy to use in symfony 2.
